Bioluminescent Comb Jelly

Like many deep sea creatures, this tiny comb jelly (Bathocyroe fosteri) has a transparent body, enabling it to blend into the surrounding waters. This ctenophore is very common around the Mid-Atlantic Ridge. More about the deep ocean can be found in the Deep Ocean Exploration section.
